frozen xfce session
I recently got a lenovo laptop (T 430S).
A couple of times while I was on xfce the system would freeze and none of the Alt+Ctrl+Bkspace or Ctrl+Alt+F1 to get to the root terminal or even Ctrl+Alt+Del would work. I'd have to turn off the power. When this occurred I had firefox open (with at most 3 or 4 tabs) and one or two X terminals, a mounted external hard drive... My RAM is 4GB, the graphic card is an Intel and the system is slackware 14.0 Problem is I'm afraid it happens randomly. I was wondering whether it's software-related or some faulty hardware. Does anybody have a clue? Thanks |
Probably faulty hardware. Did you try running memtest on that machine?

Anyways, it seems memtest did find errors: Code:
Memtest86 v4.2.0 Intel Core i5-3320M @2.60GHz |
Yeah, memtest will run until you stop it. For some memory errors, you have to run it a long time for the error to show up.

Now, I'm not so sure.
I remember having pressed the Escape key at one point, and that's when I got these errors. This time I let it run for 2 hours without pressing any key. So far there were no errors detected. The thing that confused me was this message: Code:
Pass complete, no errors, press Esc to exit To make sure I ran memtest for over 9 hours and it didn't detect any errors. So it seems the RAM is okay. And I'm stumped. |
Yesterday I tried something else.
I built and installed linux-3.9.0 It's still too early to say, but so far I didn't get any problems in my X-sessions. Still, I'd like to know what was the problem |
I found this info at

(currently running 3.9.2) I haven't experienced those random screen freezes. |
I had same lockups with the default kernel in 14.0 but I upgraded it to 3.8.x and have not had any issues. I did not upgrade any of the xorg bits either.

Installed Slackware 14 on a spare hard drive 4 days ago, and it would lock up after 1-20 minutes. So I downloaded kernel 3.9.2, the huge config from Slackware repositories online, and compiled that. System is stable and doesn't lock up anymore! So you probably just need a newer kernel. |
